Dell APEX Private Cloud can
provide faster application response
times in a VDI environment
The Dell APEX solution outperformed a comparable Amazon
WorkSpaces solution using the Login Enterprise benchmark
For organizations and institutions that provide remote virtual desktops
at scale, users need a fast and reliable platform they can depend on.
By choosing the right cloud option, organizations can provide their
users with a better virtual desktop infrastructure (VDI) experience and
faster application response times, which can lead to a more productive
workforce. With multiple cloud options available, both public and
private, it can be difficult to know which is right for your organization
and your users.
To compare the user experience and application response times of VDI
solutions hosted by Dell APEX Private Cloud and Amazon WorkSpaces,
we used the Login Enterprise benchmark, which is a tool for measuring
app performance on virtual machines (VMs). We found that the Dell APEX
solution delivered a 14.9 percent overall faster application response time
than the Amazon WorkSpaces solution we tested. Both solutions achieved
strong Login Enterprise End User Experience (EUX) scores. Our Dell
environment also supported 500 users across all four nodes while only
requiring 68.7 percent CPU usage. These results indicate that organizations
deciding which cloud option to use for their VDI could provide their users
with faster application response times and a strong user experience by
choosing Dell APEX Private Cloud.

Provide a strong user experience by
choosing Dell APEX Private Cloud
To evaluate the experience users could expect from these two VDI
environments, we used the Login Enterprise End User Experience
(EUX) score. Login VSI created the score using feedback from
humans using virtual machines. According to Login VSI, the score
is based on four actions:
• Launch a complete application with UI
until it is ready for user input
• Keyboard input processing
• CPU-heavy actions
• Actions that mix CPU and disk IO2
We found that both environments offered strong Login Enterprise
EUX performance. The Dell APEX Private Cloud environment
achieved a Login Enterprise EUX score of 7.9, which was
comparable to the 8.0 score the Amazon WorkSpaces environment
achieved. This indicates that choosing Dell APEX Private Cloud to
deploy your VDI could provide a strong experience for users.
How we tested
We used a four-node Dell APEX Private Cloud VDI cluster and an
infrastructure cluster. The infrastructure cluster hosted VMware Horizon®
,
Active Directory®
, and 20 launcher VMs. The launcher VMs initiated our
individual client workloads for each of our virtual desktops. The Dell
APEX Private Cloud cluster hosted our pool of user VMs.
We set up an Amazon WorkSpaces environment with comparable
specs. We used the Login Enterprise benchmark to evaluate the user
experience and application response time of the Dell APEX Private
Cloud and Amazon WorkSpaces VDI environments. The Login
Enterprise End User Experience (EUX) score measures the experience
that actual users might have when using a virtual machine. It is
important to know that the EUX score encompasses user experience
elements beyond application response times. The application response
time reflects how long users might find themselves waiting while
using the environment. We based our workload on the knowledge
worker workload. For more information visit https://support.loginvsi.

Private cloud vs.
public cloud
A private cloud is
infrastructure that an
organization hosts,
often on-premises. An
organization usually
hosts a public cloud off-
premises and a third-party
cloud service provider
(CSP) offers this service.
According to Dell, APEX
Private Cloud allows you
to “simplify operations
with built-in lifecycle
automation capabilities
with infrastructure owned
and deployed by Dell.”1

Unlock productivity for users working from anywhere
By reducing the amount of time VDI users spend waiting on applications, organizations can potentially increase
productivity. We totaled the average application response times for both the Dell APEX Private Cloud and
Amazon WorkSpaces VDI environments and calculated the difference. (See the science behind the report for
more details.) We found the Dell APEX Private Cloud environment offered an average of 14.9 percent overall
faster application response time than the Amazon WorkSpaces environment. This means choosing Dell APEX
Private Cloud to deploy your VDI could save your users time, which could boost productivity.
Dell APEX Private Cloud
According to Dell, APEX Private
Cloud is “perfect for getting started
with cloud or expanding your data
center out to the edge.”5
Dell
provides users of APEX Private Cloud
with a single point of contact to
assist with their cloud maintenance
and needs. Dell says that the service
provides a small footprint and
features built-in lifecycle automation.6

About Login Enterprise
The Login Enterprise platform offers a 360° agentless approach to
managing the performance, cost, and capacity of virtual desktops and
applications. Login VSI, the company behind Login Enterprise, claims
the technology offers a holistic view of the delivery chain of service,
from production to delivery and across locations, and works alongside
existing vendor, monitoring, and service desk tools.3
About Login Enterprise EUX score
According to Login VSI, the Login Enterprise “EUX score (End User
Experience score) represents the performance of any windows
machine (virtual, physical, cloud or on premises) and ranks it between
0 and 10” as a user experiences it.4
Login VSI used real human
feedback from users working on real virtual machines to develop the
metrics, so it attempts to assign a score that is an accurate assessment
of the actual experience users can expect using a virtual machine.

Conclusion
As remote and hybrid work have become more common,
providing VDI users with more secure and seamless access has
become more important. By choosing the right cloud option,
your organization can maximize the productivity of your users
and minimize the amount of down time. When we compared
the user experience and application response times of a Dell
APEX Private Cloud environment to those of an Amazon Web
Services environment, we found that the Dell APEX Private
Cloud environment achieved a similar EUX score and provided
faster application response time than the Amazon WorkSpaces
environment which could mean your users could spend less
time waiting, and more time being productive.
